I messed around with the Amiga trackers back in the day. When I look at the software available today, e.g. on my iPad, I have a hard time getting anything useful out of it. Which software are you using now?
Cross-platform, can use VSTs and samples, lively community, lua scriptability. It's pretty awesome all the way around.
I miss the 1998-era softsynth with built-in tracker Analogic, later called AXS (or was it the other way round?). http://www.pouet.net/topic.php?which=11012&page=1
This is the fastest DAW from nothing to something like a song, and for people just starting it has pretty much everything you need to make some kind of song. https://www.tracktion.com/products/waveform
